Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556876, here are decompositions:

7 + 31556869 = 31556876
19 + 31556857 = 31556876
73 + 31556803 = 31556876
97 + 31556779 = 31556876
139 + 31556737 = 31556876
223 + 31556653 = 31556876
229 + 31556647 = 31556876
397 + 31556479 = 31556876

Showing the first eight; more decompositions exist.
